Description

Technical Field

[0001] This invention relates to the field of unloading platforms for building construction, specifically to a telescopic unloading platform and its installation method. Background Technology

[0002] In multi-story building construction, unloading platforms are indispensable. Currently, unloading platforms mainly include ground-mounted, cantilevered, and hydraulic climbing types. Traditional ground-mounted unloading platforms are excessively large; safety risks and operating costs increase dramatically when the operating height exceeds 15 meters. They are also cumbersome to install and have high labor costs. Traditional cantilevered unloading platforms require pre-embedded anchor bolts in the main structure to fix the I-beams, and pre-drilled holes in the beams, connecting the platform to the lifting points with steel wire ropes to ensure stability. This not only makes the installation process cumbersome but also causes some damage to the building structure itself, affecting its integrity and safety. Traditional cantilevered unloading platforms also have high safety risks, low equipment turnover rate, require the embedding of pre-embedded parts for installation, and necessitate the traction of tower crane hooks during installation, resulting in high construction risks. Hydraulic climbing unloading platforms have disadvantages such as high cost, complex use and maintenance, slow climbing speed, and the ability to climb only along specific tracks. Furthermore, current unloading platforms cannot provide real-time weighing alarms; they only use weight limit signs to warn passengers about the load. This often leads to overloading of the unloading platform due to management oversights, resulting in safety accidents. Summary of the Invention

[0003] The purpose of this invention is to provide a retractable unloading platform and its installation method, which can solve the problems of existing unloading platforms, such as the inability to trigger overload alarms, cumbersome installation, and high construction costs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A retractable unloading platform includes a platform mounting assembly, a platform telescopic assembly, a horizontal drive assembly, a clamping assembly, a control assembly, a weighing assembly, and a telescopic drive assembly. The platform installation components are mounted on the floor slab and include two parallel main beams; The horizontal drive component is located on one side of the platform mounting component and is used to drive the platform mounting component to move horizontally. The clamping assembly includes a base rod and an adjusting rod. The base rod is detachably mounted on the platform mounting assembly, and the adjusting rod is threaded onto the top of the base rod. The weighing assembly includes a weighing beam and a weighing device. The weighing device is installed in each of the main beams. The weighing beam is installed on the weighing device. There are gaps between the top and left and right sides of the weighing beam and the corresponding side walls of the main beam. The platform telescopic assembly is slidably installed in the weighing beam. The telescopic drive assembly includes a rack, a drive gear, and a drive motor. The drive gear is poweredly connected to the output end of the drive motor. The drive motor is fixedly mounted on the platform telescopic assembly. The rack is fixedly mounted on the weighing beam. The drive gear meshes with the rack. The control component is used to control the actions of the horizontal drive component and the telescopic drive component. The weighing component transmits the total weight of the weighing platform telescopic component and the material to the control component. When the weighed weight is greater than the preset value, the alarm will sound.

[0005] Preferably, the horizontal drive assembly includes a linear drive component and an electric hub. The linear drive component is fixedly installed at the end of the platform mounting assembly, and the electric hub is rotatably disposed at the telescopic end of the linear drive component.

[0006] Preferably, a base is fixedly installed at the bottom of the main beam; a support is installed at the top of the main beam, and the bottom of the clamping assembly is installed on the support.

[0007] Preferably, both the main beam and the weighing beam have C-shaped cross-sections.

[0008] Preferably, several rollers are rotatably arranged inside the weighing beam, and the end of the platform telescopic assembly is slidably arranged between the two rows of rollers.

[0009] Preferably, the platform telescopic assembly includes end support beams, transverse connecting beams, and a support plate. Two end support beams are provided, and the two end support beams are slidably disposed within one of the weighing beams. Multiple transverse connecting beams are fixedly connected between the two end support beams, and the support plate is disposed on the transverse connecting beams.

[0010] An installation method for a retractable unloading platform, the installation method comprising the following steps: Step 1: Hoisting and positioning – The assembled platform is hoisted to the installation location as a whole. Step 2: The platform installation components are in place. After one end of the platform installation components is hoisted onto the floor slab, the electric hub is supported on the floor slab by controlling the extension of the linear drive component. The electric hub is then driven to move into the room. After moving to the installation position, the electric hub is detached from the floor slab by controlling the retraction of the linear drive component, so that the base is on the ground. Step 3: Lock the platform installation components. After the platform installation components are in place, install the clamping components. By turning the adjusting rod, make the top of the adjusting rod rest against the bottom of the floor slab above, thereby locking the platform installation components. Step 4: Remove the lifting components. After the overall tightening assembly has reached the preset strength, remove the hooks and lifting wire ropes installed on the platform telescopic assembly. Step 5: The platform retracts and the railing is installed. By controlling the rotation of the drive motor, the drive gear moves along the rack and pinion, and the entire platform telescopic assembly is retracted back to the floor slab. The guardrail is installed on the platform telescopic assembly. A rope retractor is installed on the outer facade of the upper floor slab, and one end of the steel wire rope on the rope retractor is connected to the platform telescopic assembly. Step six, work preparation: By controlling the rotation of the drive motor, the drive gear moves along the rack, extending the entire platform telescopic assembly outward to the working position.

[0011] Preferably, in step five, after the rope retractor and wire rope are installed, the horizontal drive assembly is removed; then, the anchoring end beam is installed at the tail of the platform telescopic assembly.

[0012] In this invention, the platform has an overload alarm capability to prevent safety accidents caused by overloading. The platform can be installed quickly without the need for pre-embedded parts, requiring only a floor slab.

[0013] The tightening assembly, through its adjustable base rod and adjusting rod structure, can precisely tighten the upper floor slab, significantly improving the anti-overturning capacity after installation and ensuring the structural stability of the platform during operation.

[0014] The horizontal drive assembly, through the cooperation of linear drive components and electric wheel hubs, enables the platform installation components to move and be positioned flexibly on the floor, eliminating the tediousness of traditional manual handling and significantly reducing installation difficulty, especially in high-altitude operation scenarios.

[0015] The telescopic drive assembly uses a rack and pinion mechanism to smoothly extend and retract the platform, allowing for flexible adjustment of the operating range to suit different floor heights and material handling distances. It can also directly transport materials indoors, is easy to operate, and enables rapid unloading.

[0016] The weighing component monitors the overall weight of the platform's telescopic components and materials in real time. When the weight exceeds the preset value, the alarm will sound in time, effectively avoiding structural damage or safety accidents caused by overload and controlling operational risks from the source. The platform's telescopic components are slidably installed inside the weighing beam, and a gap is reserved between the weighing beam and the main beam, reducing interference factors during weighing, ensuring accurate weight measurement, and providing reliable data support for safety monitoring.

[0017] The installation method involves hoisting into place, adjusting the platform installation components, and tightening and locking, enabling rapid assembly and fixation of the platform. The horizontal drive component can be removed in the later stages of installation to avoid occupying working space. The addition of a rope retractor and wire rope further enhances the stability of the platform's telescopic components. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 11 The telescopic unloading platform shown includes a platform mounting assembly 1, a platform telescopic assembly 2, a horizontal drive assembly 3, a clamping assembly 4, a control assembly 5, a weighing assembly 6, and a telescopic drive assembly 7.

[0020] Platform mounting assembly 1 is mounted on floor slab 8. Platform mounting assembly 1 includes two parallel main beams with a C-shaped cross-section, and the openings of the two main beams are positioned opposite each other. A base 10 is fixedly mounted at the bottom of the main beams; a support 11 is fixedly mounted at the top of the main beams, and the bottom of the clamping assembly 4 is mounted on the support 11. A battery for supplying power to the platform operation is also located at one end of platform mounting assembly 1.

[0021] The horizontal drive assembly 3 is located on one side of the platform mounting assembly 1 and is used to drive the platform mounting assembly 1 to move horizontally. The horizontal drive assembly 3 includes a linear drive component 30 and an electric wheel hub 31. The linear drive component 30 is fixedly installed at the end of the platform mounting assembly 1, and the electric wheel hub 31 is rotatably mounted on the telescopic end of the linear drive component 30 via a bracket. The linear drive component 30 is preferably a hydraulic cylinder, but a pneumatic cylinder or an electric push rod can also be used as a substitute. When the electric wheel hub 31 is energized, its forward, backward, and stop movements can be controlled via a remote control. The control system of the electric wheel hub 31 is integrated into the control assembly 5.

[0022] The clamping assembly 4 includes a base rod 40 and an adjusting rod 41. The base rod 40 is detachably mounted on the platform mounting assembly 1, and the adjusting rod 41 is threaded onto the top of the base rod 40. Tightening the adjusting rod 41 adjusts the overall height of the clamping assembly 4, allowing it to be pressed against the bottom of the upper floor slab for clamping support. Four base rods 40 are provided, with two base rods on the same side reinforced by a transverse tie rod. A pad is placed on the top of the adjusting rod 41 to increase the contact area with the floor slab 8.

[0023] The weighing assembly 6 includes a weighing beam 60 and a weighing device 61. A weighing device 61 is installed within each main beam, and the weighing beam 60 is mounted on the weighing device 61. Gaps exist between the top and left and right sides of the weighing beam 60 and the corresponding sidewalls of the main beam. These gaps prevent inaccurate measurements due to contact between the weighing beam 60 and the main beam during weighing. The weighing device 61 is a load cell, electrically connected to the control assembly 5 via a control line. The load cell transmits the measured weight information to the control assembly 5. The weighing beam 60 has a C-shaped cross-section, with its opening located on the same side as the opening of the main beam.

[0024] Two rows of several rollers 12 are rotatably arranged inside the weighing beam 60 via pins. The end of the platform telescopic component 2 is slidably arranged between the two rows of rollers 12, and the resistance of sliding friction is reduced by rolling.

[0025] The platform telescopic assembly 2 is slidably disposed within the weighing beam 60. The platform telescopic assembly 2 includes end support beams 20, transverse connecting beams 21, and support plates 22. Two end support beams 20 are provided, each slidably disposed within the weighing beam 60 on its corresponding side. Multiple transverse connecting beams 21 are fixedly connected between the two end support beams 20, and the support plate 22 is fixedly disposed on the transverse connecting beams 21. The platform telescopic assembly 2 is used to support materials.

[0026] The telescopic drive assembly 7 includes a rack 70, a drive gear 71, and a drive motor 72. The drive gear 71 is poweredly connected to the output end of the drive motor 72. The drive motor 72 is fixedly mounted on the platform telescopic assembly 2 via a bracket. The rack 70 is fixedly mounted on the weighing beam 60, and the drive gear 71 meshes with the rack 70. When the drive motor 72 is energized and rotates, it drives the drive gear 71 to rotate. Through the meshing transmission between the drive gear 71 and the rack 70, the platform telescopic assembly 2 moves horizontally. The drive motor 72 is poweredly connected to the drive gear 71 via a pair of bevel gears.

[0027] Control component 5 controls the actions of horizontal drive component 3 and telescopic drive component 7. Weighing component 6 transmits the total weight of the weighing platform telescopic component 2 and the material to control component 5. When the weighed weight exceeds a preset value, alarm 9 sounds an alarm. Control component 5 uses a microcontroller or PLC programmable controller, and alarm 9 is a buzzer alarm. Control component 5 can be installed on platform mounting component 1 or on the building structure.

[0028] like Figures 1 to 11 The method for installing a retractable unloading platform includes the following steps: Step one: hoisting and positioning. Attach the lifting wire rope to the lifting lugs of the platform's telescopic assembly. Using the hook and hoisting equipment, hoist the assembled platform to the outside of the installation location, awaiting the next installation step. Figure 6 As shown.

[0029] Step two: Platform installation component 1 is in place. After one end of platform installation component 1 is hoisted onto floor slab 8, the extension of the linear drive component 30 is controlled to support the electric hub 31 on floor slab 8. The electric hub 31 is then driven to move indoors. Once it reaches the installation position, the retraction of the linear drive component 30 is controlled to detach the electric hub 31 from floor slab 8, allowing all bases 10 to land on the ground. Figure 7 As shown.

[0030] Step 3: Lock platform installation component 1. After platform installation component 1 is in place, install the tightening component 4. By turning the adjusting rod 41, the top of the adjusting rod 41 is pressed against the bottom of the upper floor slab 8, thereby locking platform installation component 1. Figure 8 As shown.

[0031] Step four: Dismantle the lifting components. After the overall tightening assembly 4 has reached the preset strength, remove the hooks and lifting wire ropes installed on the platform telescopic assembly 2, such as... Figure 9 As shown.

[0032] Step 5: The platform retracts and the railing is installed. By controlling the rotation of the drive motor 72, the drive gear 71 moves along the rack 70, retracting the entire platform telescopic assembly 2 back onto the floor slab 8. The guardrail 13 is then installed on the platform telescopic assembly 2. A rope retractor 14 is installed on the outer facade of the upper floor slab 8, with one end of the steel wire rope 15 on the rope retractor 14 connected to the platform telescopic assembly 2. Figure 10 As shown. The rope retractor 14 is a commercially available wire rope retractor.

[0033] After the rope retractor 14 and wire rope 15 are installed, remove the horizontal drive assembly 3; then install the anchoring end beam 16 at the tail of the platform telescopic assembly 2.

[0034] Step six, work preparation: By controlling the rotation of the drive motor 72, the drive gear 71 is driven to move along the rack 70, extending the platform telescopic assembly 2 outward to the working position. Figure 11 As shown. In this state, the wire rope 15 is taut and participates in the overall platform's stress distribution. The rope retractor 14 is responsible for winding up excess wire rope when the platform's telescopic assembly 2 retracts. The operation of the rope retractor 14 is performed manually.

[0035] The above embodiments are merely illustrative of the concept and implementation of the present invention and are not intended to limit it. Under the concept of the present invention, technical solutions without substantial changes are still within the scope of protection.
